Application October 8, 1934, Serial No. 747,448 1 claim.' (c1.15s-'106)- 'Ihis invention relates to gas burners and has for theprimary object the provision of a device of the above stated characterwhich will efficiently mix air and gas to produce a highly combustiblemixture capable of producing maximum heat units from a comparatively lowpressure gas supply.

With these and other objects in View this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention reference is to be had tothe following description and accompanying drawings, in which Figure 1is a side elevation partly in section illustrating a burner constructedin accordance with my invention.

Figure 2 is a fragmentary top plan View illustrating the same.

Figure 3 is a fragmentary plan View partly in section illustrating oneof the sections of the manifold and having associated therewith a seriesof mixing units.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a plan view illustrating a base plate.

Figure 6 is a plan view illustrating the pedestal or support on whichthe base plate and other units of the device are mounted.

Referring in detail to the drawings, the numeral I indicates a supportconsisting of a vertically arranged post 2 removably secured to a base3. Secured to the upper end of the post 2 is a collar 4 provided withscrew threaded sockets to receive the screw threaded ends of radiallyarranged supporting arms 5. The arms have mounted thereon a base plate6, centrally apertured to receive the collar 4, the upper surface of thelatter being flush with the upper surface of the base plate 6. It ispreferable that the base plate 6 be constructed of sections joinedtogether, as shown at l, to facilitate the assembling of the base plateto the collar 4. The base plate supports a manifold 8 of annularformation and consisting of semi-circular tubular sections 9 each havingits ends closed by plugs which are preferably welded in said ends of thesections of the manifold, as shown in Figure 3. Integral with thesections of the manifold are depending pipe sections I0 which extendthrough openings in the base plate 6 and are provided with couplings I Iby which supply pipes (not shown) may be connected to the manifold.Secured to the sections 9 of the manifold are a series of nipples I2,the latter being preferably threaded into openings formed in thesections of the manifold and are in turn threaded to mixing units I3.The nipples I2 support the mixing units I3 in upwardly and outwardlydisposed directions with respect to the manifold and each unit consistsof a body provided with bulged portions forming therein primary andauxiliary mixing chambers I4 and 5. One end of the body is recessed andscrew threaded to receive the nipple and como municative with the nippleis the bore I6 of a jet I'I terminating approximately centrally of theprimary mixing chamber I4. Air ports I8 are arranged in the walls of themixing cham'- bers I4 and I 5, the air ports of the mixing chamber I4being disposed rearwardly of the free end of the jet Il. Cast integrallywith the mixing chamber I4 and extending into the mixing chamber I5 is anozzle I9 disposed in alignment with the jet I1 and terminatingsubstantially centrally of the mixing chamber I5. The outer end of thebody is shaped to form a nozzle 20 aligning with the nozzle I 9. Theports I 8 of the mixing chamber I 5 are arranged rearwardly of the freeend of the nozzle I9. The gas from the manifold enters 25 the primarymixing chamber I4 by way of the jet I1 and this gas passing towards andthrough the nozzle I9 draws air through the ports I8 of the primarymixing chamber I4. The air and gas thoroughly mix and enter theauxiliary mix- 30 ing chamber I5 with considerable velocity. Additionalair is furnished the mixture in the auxiliary mixing chamber I5 by theports I8 thereof so that the fuel escaping from the nozzle zo will be ofa highly Combustible nature, it being 5 understood that the fuel burnsat the end of the nozzle 20 and is capable of producing maximum heatunits.

A deilector 2| consists of a conical-shaped portion 22 and an annularshaped portion 23, the latter being arranged within the manifold andresting upon the base plate 6 with the conical portion incliningupwardly over the mixing units. The deector being of the shapedescribed, will deflect air currents upwardly and outwardly with respectthereto and said air currents aid in directing the ames from the mixingunits in a corresponding direction. Carried by the deflector on theannular portion 23 thereof are bars 24 which overlie the manifold 8 andaid in retaining the device in proper assembled position, the outer endsof said bars being bent upwardly and outwardly at approximately the sameinclination as the mixing units and the 55 conical-shaped portion 22 ofthe deilecto'r. The arms 24 project a short distance beyond or outwardlyof the mixing units and this arrangement of the parts maintains thedevice when assembled in a centrally located position in a furnace insuch manner that the burner units are maintained at the proper distancefrom the walls of the furnace, for the greatest degree of eciency.

A burner of the character described can be shaped or designed to t a rebox either of annular formation; rectangular shape or a box of any othershape which may be desired in 'the construction of a furnace.

Having described the invention, I claim:

A gas burner including a stand, a horizontally disposed base removablymounted on said `stand and including detachably connected semicircularshaped sections, a deflector including an annular portion resting on thebase and a frusto-conical shaped portion extending upwardly and outofsaid mixing chambers having air ports and being of substantiallyspherical shape, and horizontally disposed arms secured to the annularportion of the deflector and resting on the manifold between certain ofthe mixing units and k'having the free'ends thereof bent to extendupwardly and outwardly from the base and arranged outwardly of themixing units.
